Misc. Comments

Neither the cover page nor the title page (second page in the scan) list the composer Karl Adolf Lorenz. On the first page of music in the area which typically lists the composer and opus (and sometimes the title) that information is listed very oddly in this fashion:

Moritz, Op.7
(C. Ad. Lorenz)
Contrast that with Lorenz's Op.25 that was published by Schlesinger in 1884 (only one year later) in which is found the following:
C. Ad. Lorenz, Op.25.
Hofmeister's Musikalisch-literarischer Monatsbericht lists Streiche (pranks/tricks) 1 and 2 as being Opp.1 and 2 by Moritz (Hofmeister's Monatsbericht (1883), p.348) and lists the publication of the fifth prank as being Moritz's Op.11 (Hofmeister's Monatsbericht (1887), p.355.
Evidently, Lorenz was having his own joke by having the cartoon character Moritz listed as the composer.

Lorenz had had an earlier Op.7 published in 1868, 3 piano pieces Wie es euch gefällt book 1.
